Carvin P series : Is it for me?

As of right now, I own 2 Carvins. A B4 and an LB76, both of which have your standard J pups.

I'm looking to get a Carvin LB70, then replace the neck on my B4 to fretted. I love the tone I'm getting from my B4 now, but I wouldnt mind having more versatility. So I was looking at the P series. My problem is, am I going to lose the tone I have now? Will I still be able to make it sound as close to what I can now?

You'd probably get close enough to the tone of your other Carvins (with the standard J pickups) by splitting the coils of the MM pickup (thereby putting it in single coil mode) and blend-knobbing-out the piezos.
